Red Hat Product Errata RHSA-2007:0892 - Security Advisory
Issued:
2007-09-07
Updated:
2007-09-07

RHSA-2007:0892 - Security Advisory

  • Overview
  • Updated Packages

Synopsis

Important: krb5 security update

Type/Severity

Security Advisory: Important

Topic

Updated krb5 packages that correct a security flaw are now available for
Red Hat Enterprise Linux 5.

This update has been rated as having important security impact by the Red
Hat Security Response Team.

Description

Kerberos is a network authentication system which allows clients and
servers to authenticate to each other through use of symmetric encryption
and a trusted third party, the KDC. kadmind is the KADM5 administration
server.

The MIT Kerberos Team discovered a problem with the originally published
patch for svc_auth_gss.c (CVE-2007-3999). A remote unauthenticated
attacker who can access kadmind could trigger this flaw and cause kadmind
to crash. On Red Hat Enterprise Linux 5 it is not possible to exploit this
flaw to run arbitrary code as the overflow is blocked by FORTIFY_SOURCE.
(CVE-2007-4743)

This issue did not affect the versions of Kerberos distributed with Red
Hat Enterprise Linux 2.1, 3, or 4.

Users of krb5-server are advised to update to these erratum packages which
contain a corrected backported fix for this issue.

Solution

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.

This update is available via Red Hat Network. Details on how to use
the Red Hat Network to apply this update are available at
http://kbase.redhat.com/faq/FAQ_58_10188
